Delete the whole Business partner master data from CRM which is around 2 crores

Hi,

I have BP master data in crm which is around Rs.2 crores data . So for deleting all that data I am using the method to set delete flag by using the tcode (BUPA_DEL ) . And I kept this task as back ground job it was taken around 3 full days of time but still it was running.

Is there any method to delete this whole data with no archiving?

Thanks in advance,

Praveen Chitturi.
